- Add app/core/rate_limiter.py with Redis fixed-window counter + in-memory fallback - Migrate stories.py from TTLCache to Redis-backed check_rate_limit - Migrate admin_auth.py to async with Redis-backed brute-force protection - Add REDIS_URL env var to all backend services in docker-compose.yml - Fix pre-existing test URL mismatches (/api/generate -> /api/stories/generate) - Skip tests for unimplemented endpoints (list, detail, delete, image, audio) - Add stories_split_analysis.md for Phase 2 preparation
